We have a customer where we print some text on the first page of an PDF. The Problem is the customer has also some Portfolio PDFs and PDFs which looks like they're using XFA Formulars (which are also not supported what I've read) where the PDFs get corrupted after saving.

Is it possible to dedect if a PDF is using features not supported by QuickPdf, so that we can ignore the PDFs?

PS: When I open my Sample Portfolio file and a call GetPageText, it returnes

Zur optimalen Anzeige dieses PDF-Portfolios sollte es in Acrobat oder Adobe Reader ab Version 9 geönet werden.

which is German and means Install Acrobat Reader X for using PDF-Portfolios

Hi!

There is an XFA-function to count the xfa-formfields.

The other thing: Do it like you've done it...

Textextraction and searching for "Acrobat Reader X"

for example.

Open these files with notepad or something similar

searching for special xfa-details. If you've found some

you can check all future pdf-documents with these

specifications reading the pdf-content into a stream or

string right from harddisk.

Cheers and welcome here,

Ingo

As Ingo has mentioned - QP.GetXFAFormFieldCount() will tell you if there are any XFA form fields in the file.

Another option is to check the Producer string - QP.GetInformation(6); which will return something like "Adobe LiveCycle Designer 9.0". - There will be different version numbers for LiveCycle but it might give you another option to detect the XFA forms based PDF's.

Thanks, GetInformation(6) worked for me (my version has no GetXFAFormFieldCount()).

The solution is a bit of a hack and I'm not shure if it will not result in problems in the future, will there be a method like IsFilePortfolio or IsFileSupported in future versions of quickPdf?

Hi,

I have the sample documents now, but is there a way to send them to you directly? These sample documents are customer documents (even with removed Data) and I do not want to upload them visible for a public forum.
